Include the calculator name and the number that looks wrong, or a short description of what you are trying to calculate.
Common reasons to reach out
Found a number that looks wrong?
Tax rates and thresholds change. If a figure in one of our calculators looks off, send us the IRS or CRA source and we will verify and update it, usually within 24 hours.
Want to request a calculator?
Tell us what calculation you keep doing by hand or in a spreadsheet. If it is useful for freelancers and side hustlers broadly, we will build it.
Partnership or press inquiries?
We are happy to talk about embedding our calculators on your site, content partnerships, or media coverage of the project.
General questions
Not sure what calculator to use, or have a question about how a specific result was calculated? Reach out and we will explain the math.
